ลองดูแล้วกันครับเพื่อเป็นแนวทางได้ครับโดยผมลอง จำำลองข้อมูลตามที่คุณ help me ได้ให้มาสัก 2 บรรทัดCode (C#) protected void Page_Load(object sender, EventArgs e)
{
DataTable dtHeader = new DataTable();
dtHeader.Columns.Add("id_core");
dtHeader.Columns.Add("id_evaluator");
dtHeader.Columns.Add("score");
DataRow dr = dtHeader.NewRow();
dr["id_core"] = "C001";
dr["id_evaluator"] = "O0000000001";
dr["score"] = "4";
dtHeader.Rows.Add(dr);
dr = dtHeader.NewRow();
dr["id_core"] = "C001";
dr["id_evaluator"] = "O0000000001";
dr["score"] = "5";
dtHeader.Rows.Add(dr);
dr = dtHeader.NewRow();
dr["id_core"] = "C002";
dr["id_evaluator"] = "O0000000002";
dr["score"] = "4";
dtHeader.Rows.Add(dr);
dr = dtHeader.NewRow();
dr["id_core"] = "C002";
dr["id_evaluator"] = "O0000000002";
dr["score"] = "3";
dtHeader.Rows.Add(dr);
DataTable dtDetail = new DataTable();
dtDetail.Columns.Add("id_core");
dtDetail.Columns.Add("score1");
dtDetail.Columns.Add("score2");
string core = "";
string evaluator = "";
string score1 = "";
string score2 = "";
int i = 0;
foreach (DataRow drs in dtHeader.Rows)
{
string id_core = drs["id_core"].ToString();
string id_evaluator = drs["id_evaluator"].ToString();
if (id_core == core && id_evaluator == evaluator)
{
score2 = drs["score"].ToString();
DataRow drDetail = dtDetail.NewRow();
drDetail["id_core"] = core;
drDetail["score1"] = score1;
drDetail["score2"] = score2;
dtDetail.Rows.Add(drDetail);
core = ""; score1 = ""; score2 = ""; i = 0;
}
else
{
core = id_core;
evaluator = id_evaluator;
score1 = drs["score"].ToString();
}
}
dtDetail.DefaultView.Sort = "id_core ASC";
GridView1.DataSource = dtDetail;
GridView1.DataBind();
}
